I Returned as a God

I was thrust into an unknown world by a god and forced to save it, under the promise that if I were successful in saving the world, I’d be sent back to my home…
However, after doing the god’s bidding, I was betrayed. With no other options left, I had to escape through a dimensional rift.
“Just you wait! I’ll definitely come back!”
That’s how I… Returned as a God.
